Have you asked him (or her) whether it was intentional?
I am pretty sure it is intentional. The first instance was Lent and I was sitting right in front of the person and beside the Bishop (Service at the Tomb, so we are not at the altar and I was serving) when the person read the reading and there was a part that said "men" only (this was about the dried bones if I remember correctly) and the person said "men" paused for half-a-second, and then added on-the-fly, "and women". Literally in my mind I said, "WTF?!"
Okay, fine, I let that slide. I know that there are places in the Liturgy today that we use "brothers and sisters" instead of "brethren" so I said it is not a big deal. But this Sunday I had sore throat so I wasn't able to give the usual congregation the pleasure of listening to my singing voice, so I stood quietly letting others do the singing. That is when I noticed. At the First Antiphon, "Shout to the Lord all the earth, sing now to His Name, give glory to His praise.." Then I heard the person say rather clearly, "sing now to God's Name, give glory to God's praise." Then again at the Anaphora, "Holy, Holy, Holy... blessed is He who comes..." becomes, "blessed is the One..." Then again before Communion, "Blessed is He who comes in the Name of the Lord, God the Lord has appeared to us." Again it becomes, "blessed is the One."
And we're a Latinized parish, we have pews with kneelers, and we have the service books in every pew. Everyone sings with the books open.
I know I'm planning to leave soon for Orthodoxy but I don't want to leave without bringing this up, for their own good.
